Letters Patent No. 102,408, dated April 26, .1870.

IMPROVED CARRIAGE-AXLE LUBRICATOR.

The Schedule referred t'o in these Letten Patent and making part of the same.

To all whom z'tmay concern:

Be it known that I, JOHN KILLEFER, of West Richfield, Summit county, Ohio, have invented certain new and useful Improvements in the Mode of Lubricating Carriage-Axles and that the following is a full, clear, and exact 'description of my invention.

Nature and Objects of Invention.

ltion, but preventing any oil from leaving the oil-cup when the carriage is still, which prevents any Waste of the oil,and obviates the danger of flooding the spindle and causing drippings at its ends.

. The second part ot' my invention relates to the combiuation'of the oil-cup with the axle-clip and wooden par't of the axle, whereby I obtain a'screw-bearin'g for the shank of the oil-cup in a metallic collar, which surrounds and unites. the two parts of the axle, thus securing a much stronger attachment for the oil-cup than would be obtained. by simply screwing it into the wood; en part of .the axle..

The third part of my invention relates to the arrangement of a leather or other equivalent washer in a cavity in the wooden part of the axle, and around the lower end of the hole for the shank of the oil-cup, said washer being arranged in said cavity before the wooden part is placed on the iron axle, whereby I obtain au oil-tight connection between the oil-passage in the neck of the oil-cup and the oil-channel in the iron axle, without the necessity of tapping a hole in the iron axle, to receive the shankof the oil-cup, as has heretofore been the practice, and `which materially weakened the strength of the iron axle, by cutting out metal at a point liable to receive the most severe strains.

Description of Accompanying Drawings. Figure 1 is'an elevation' of a portion of the carriageaxle embodying my invention.

Figure 2 is a longitudinal section of the same.

Figure 3 is an elevation of the same, with'hub-box removed. 1 A

Figure 4 is a transverse section of the same, taken through the centre of the oil-cup.

General Description. The iron axle R is of an ordinary form, and has the spindle, A formed at its end, with the intervening spindle-collar' c and the threaded -end D, for the nutl E, Which holds the hub-box B on the spindle. The oil-channel G, by which the oil is conveyed to the spindle from the oil-cup, is drilled from the point b on the bearing-face ofthe spindleA to the point a, on the top of the iron axle R, and back of the spindlecollar c, as shown in fig. 2. r

V- The wooden part Cof the axle is tted on the iron axle R, Where it is held by the clip O, which passes through the cross-bar M, and is held by the nuts NN.'

The hole f, for the shank of the oil-cup J, is bored in the wooden part O, so as to bring the center of the oil-cup directly over the end a of the oil-channel in the iron axle, and a hole is drilled in the clip O, to corre-vl spoud with that in the wooden part 0, as shown.

The cavityd is formed'in the wooden partO around the lower end of the hole f, and in this vcavity is fitted the washer I, as shown in figs. 2 and 4, so that, when the wooden part C is placed on the iron axle R, the washer I is secured -in theproper position to serve as a packing between the shank of the oil-cupJ and the iron axle R.

A hole is formed in the center of the washer I, to allow of the passage of the oil in the oil-cup to the oilchannel in the iron axle, as shown in figs.' 2 and 4.

The form of the cavity d and washer I is not mate rial, but they are vconveniently made of a circular form, the cavity d being made by boring a hole of a diameter of from a quarter to a half-inch greater than. that of the hole f, and of a depth. equal tothe thick` ness of the washer Land the washer I being simplya round leather or rubber washer, made to fit closely in the hole d. p

A thread is cut on the shank of the oil-cup J, and a corresponding thread is cut in the hole f in the clip 0 and woodenpart G, so that, by screwing the shank of the oil-cup into the hole f, it is firmly secured in position, and its end islbrought down onto the washer I,

so as to compressvsaid washer between the end of the oil-cup, shank and the iron axle, thus making an oiltight'joint between the oil-cup and iron` axle.

The 4bottom of the interior cavity ofthe oil-cup has the form of a iiattened hemisphere, the central portion e .e being nearly flat, but having a slight slope from all sides toward the oil-passage H, which is a small hole drilled through the neck of the oil-cup, and with square edges at its upper end, instead of beingreamed out at said upper end in a'funnel shape.

.The Vball-valve L is simply a round metal ball, of a diameter from two to three times as great as that of the oil-passage H,so that, when said ball sits over the upper end of said oilpassage,' it closes it completely, but does not sink down into said passage to any extent, from which it is seen that a slight vibrationof the axle will be suicient to canse it to roll from its seat onto the nearly flat surface e e in the oil-cup.

The oil cup J is provided with a screw-cover, K, which is readily unserewed and removed, when the oilcup requires refilling. I

The groove Q is cntalong the upper side of the spindle A, to receive the accumulation of the dirt gathering in the hub-box B, and the washers F and P are placed on the spindle A, to keep dirt and dust from working in onto the spindle, aswell as to preventthe oil from working out.

From the foregoing description, it will be evident that when the carriage is in motion, the vibrations and jarrings to which the axle A R is subjected will keep the ball L rolling about on the surface e e, thus allowing the oil to pass down through the hole H and oil-channel G to the spindle A, and insuring the proper lubrication of the sat'ne, but that, as soon as the carriage is stopped, the axle A R is free from vibration, the slight incline ofthe surface e e will cause the ball L to roll onto the hole H, thus closing the passage from the oil-cup and preventing the oil from ruiming outand flooding the spindle A.

Claim., L

passing through the clip O and wooden part C,

of a attened hemisphere, the several parts being so constructed and arranged as that the vibrations ofthe carriage-axle shall cause the said ball to act as ,a rollin g-valve regulating the-passage of the oil from the oilcup to the spindle, substantially as is herein. specified.

2. The combination of the iron axle R, wooden part O, axleclip O, and oil-cup J, the shank of said oil-eng an the several parts being arranged substantially as and for the purpose. specified.

3. Thearrangement of the washer I inthe cavity d, at the lowerend of the hole f in the wooden part O of the axle, for the purpose of insuring an `oil-tight connection between the iron axle R and oil-cup J,

whenever said oil-cup is screwedinto its proper posi-- tion, substantially as herein specified. l y

4. The combination of the iron axle A R, provided with an oil-channel, G, extending from a point, b, on the bearing-face of the spindle A, to a point, a, on the upperface of the axle R, and behind the spindle collar c, wooden part O, axle-clip O, and oil-cup J, provided with the rolling ball-valve L, the several parts heilig constructed, arranged, and operating `substantially as and for the purpose specified.

As evidence of the foregoing I have hereunto set my hand in presence of two witnesses, this 24th day of January, 1870.
